This module measure only 1.75"x1.6" but packs a surprising amount of technology into it's little frame. At the heart is a powerfull GSM cellular module (we use the latest SIM808) with integrated GPS. This module can do just about everything

Sounds delicious, right? So we plated this fine module onto a little breakout with all the extras you need to make your next project shine

Onboard LiPoly battery charging circuitry so you can take your project on the go. Use any 500mAh+ LiPoly or LiIon battery and recharge over the MicroUSB when necessary. Two LEDs let you know when its charging and done

Standard 4-pole TRRS headphone jack. Use any 'Android' or 'iPhone'-compatible headset with mic

Breakouts for external 32Ω speaker and electret mic if you don't want to use a headphone

Level shifting circuitry so you can run it with 2.8V to 5V logic.

Vibrational motor (buzzer) driver so you can have noiseless notifications

uFL connections for external antennas

Indicator LEDs for power and network connectivity

Standard SIM slides into the back

On its own, this module can't do anything. It requires a microcontroller to drive it! We suggest and use an Arduino but any 3-5V microcontroller with a UART can send and receive commands over the RX/TX pins.

You will also need some required accessories to make FONA work. These are not included!

There's also some recommended accessories. They are not required but chances are you'll want them!

TRRS 4-Pole Headset - Any 'iPhone' or 'Android' compatible (but not iPhone original) should work. We tried about 10 different ones, and basically the more expensive once are more comfortable and louder but our official iPhone headset mic did not work.
